Support "Graduated Payments" in Searchie Payments (Stripe supports it, but Searchie bugs out when it's used)

Currently, if a payment plan is set to "Graduated Payments" in Stripe (meaning the first user seat is $XX.00 but the 2nd is $X.00), Searchie bugs and breaks and charges $0 for the plan. It only supports standard payments, not graduated. This is really important to me because I sell a program that is $95 per month for the first user, but $2 per month for each additional user [to encourage full company adoption].
